6 Claims.

This invention has to do with the Way in which the sealing vstrips are attached to the bottom rails of wooden car window sash.

The purpose of the invention is to provide improved strip attaching means, in the form of a novel metal retainer, which is very simple in construction, can be manufactured at small cost, permits the sealing strip to be applied quickly with a minimum number of labor operations, allows the strip to be replaced readily without removing the sash from its guides, eliminates the use of screws along the edge of the rail and consequently does away with the danger of hand injuries by reason of projecting or mutilated screw heads, and prevents the fastening means from being subjected to sheering stresses when the sash is brought down forcibly on the sill.

While the foregoing statement is generally indicative of the nature of the invention, other more specific objects and advantages will be evident to those skilled in the art upon a full understanding of the construction, arrangement and purpose of the improved strip attaching means.

In order that the invention may be readily understood, two slightly diiferent embodiments of the same are presented herein, but it will of course be appreciated that the invention may be incorporated in other structurally modified forms coming equally within the scope of the appended claims.

In the accompanying drawing:

Fig. 1 is an outside face view of a wooden car window in which the bottom rails of the outer and inner sash have been equipped with sealing strips in accordance with the invention;

Fig. 2 is a vertical section through the window, taken on approximately the line 2--2 of Fig. 1; and

Fig. 3 is a somewhat similar section through the bottom rail of a single sash, showing a slightly modied'embodiment of the invention.

The window which is illustrated in Figs. 1 and 2 is an ordinary railway car window which is equipped with wooden sash l() and 11. As will be observed in those views, the inner sash 11, instead of having a weather strip of rubber, felt or leather screwed or tacked along the lower edge of the bottom rail 12 in the usual manner, is rabbeted along both faces at 13 and 14 and is embraced throughout such rabbeted portion by the upper side portions 15 and 16 of a special metal retainer 17 of generally H-shaped cross section.

The lower side portions 18 and 19 of the retainer embrace the upper portion 20 of a moulded rubber sealing strip 21 and are provided with narrow inturned flanges 22 and 23 which interlock vertically with grooves 24 and 25 in the sides of the strip. The retainer 17 is disposed hush with the portions of the rail and strip above and below the same, thereby giving the assembly a neat unitary appearance, and permitting the same to work smoothly in the guides at the sides of the sash.

The upper side portions 15 and 16 of the retainer are provided at intervals with aligned apertures 26 and 27, and the rabbeted portion of the bottom rail embraced by such upper side portions is likewise provided with apertures 28 in register with the apertures 26 and 27. Screws 29 of twopart telescopic construction are inserted in the apertures 26, 27 and 28 and are drawn up tightly, securing the retainer' rmly to the rail.

By attaching the rubber sealing strip 21 to the bottom rail 12 in the above described manner, replacement may be easily and quickly eifected by merely raising the sash and taking out the screws 29. Removal of the screws permits the retainer 17, with the no longer serviceable sealing strip therein, to be dropped down and replaced by an identical retainer which is either a new one or else one which has previously been reconditioned in the shops by the insertion therein of a new sealing strip. No screws, nails or other possibly projecting metal parts being present along the lower cushioned edge of the bottom rail, there is no danger of injuries to the hands of passengers, which so frequently have taken place in the past with the bottom rail sealing strip constructions heretofore employed with wooden sash. When the sash is forcibly brought down against the sill, the sealing strip 21 will act directly against the lower edge of the bottom rail through the equalized pressure distributing medium of the retainer 17, owing to the vertically abutting relationship existing between the parts, and the attaching screws 29 will thereby be relieved of the sheering stresses to which the attaching means ordinarily employed in connection with weather strips for wooden sash are subjected.

The outer sash 10 is shown as equipped with the same kind of special sealing strip retainer 17 as the inner sash, the only difference being that an outside lift plate 30 is added to permit the outer sash to be raised for washing or repair. The plate 30 is of L-shaped cross-section and the downwardly extending portion 31 of the plate is lapped behind the upper outside ange 15 of the retainer and is rigidly secured thereto by rivets 32. To make room for the lift plate 30, the front portion of the bottom rail at the location of the plate is additionally recessed at 33.

In the modiiication shown in Fig. 3, the retainer 34, instead of being of extruded or cast metal form, is of sheet metal form, and is made in three parts 35, 36 and 37. The parts 35 and 36 are substantially flat strips which form the sides of the retainer, while the part 37 is an inverted U-shaped strip which forms the cross web of the retainer and is provided with inturned anges 38 which are engaged by reversely bent flanges 39 on the lower edges o1 the side strips. This construction provides a secure and readily detachable mounting for the sealing strip 40, yet is very inexpensive to manufacture and is quite light in weight.

I claim:

1. The combination, with the bottom rail of a wooden sash, and a sealing strip for the same, of a metal retainer of generally H-shaped cross section which is substantially the same width as the rail and sealing strip and embraces in its upper portion the lower edge of the rail and in its lower portion the upper edge of the strip.

2. The combination, with the bottom rail of a wooden sash, and a sealing strip for the same, of a metal retainer which is the same width as the rail and sealing strip and embraces in its upper portion the lower edge of the rail and in its lower portion the uper edge of the strip, and means above the strip in vertically spaced relation to the latter for securing the retainer to the rail.

3. The combination, with the bottom rail or" a wooden sash, and a sealing strip for the same, of a metal retainer of generally H-shaped cross section which embraces in its upper portion the lower edge of the rail and in its lower portion the upper edge of the strip, said retainer being provided in its upper portion with aligned pairs of apertures for the reception of two-part clamping screws passing through the rail and being provided at its lower edges with inturned iianges for interlocking coaction with grooves in the sides of the strip.

4. The combination, with the bottom rail of a wooden sash, and a sealing strip for the same, of

a metal retainer of generally H-shaped cross section which is the same width as the rail and sealing strip and embraces in its upper portion the lower edge of the rail and in its lower portion the upper edge of the strip, said rail being rabbeted at its lower edge along both faces, and said retainer being provided in its upper portion with aligned pairs of apertures for the reception of two-part clamping screws passing through the rail, and being provided at its lower edges with inturned flanges for interlocking coaction with grooves in the sides of the strip.

5. As an article of manufacture, a metal retiner for securing a rubber sealing strip to the lower edge of the bottom rail of a wooden sash, which retainer is generally H-shaped in cross section and of substantially the same width as the rail and sealing strip and is adapted to embrace in its upper portion the lower edge of the rail and in its lower portion the upper edge of the strip.

6. As an article of manufacture, a metal retainer for securing a rubber sealing strip to the lower edge of the bottom rail or" a wooden sash, which retainer is generally H-shaped in cross section and is adapted to embrace in its upper portion the lower edge of the rail and in its lower portion the upper edge of the strip, said retainer being provided in its upper portion with aligned pairs of apertures for the reception of two-part clamping screws adapted to pass through the rail, and being provided at its lower edges with inturned flanges which are adapted to interlock within grooves in the sides of the strip.
